New update - Opera beta 58.0.3135.45 ;-)
The change log, and the announcement.
"It’s time for beta update, which contains some crash fixes.
Also, from now on, the “Continue where you left off” option in Settings will be named “Retain tabs from previous session”.
Tab preview should work now in this update.
Known issue: DNA-74949: [Mac 10.10] Pixelated COPY | SEARCH popup."

New features? i request some features from Opera 43 but i did see not anything. opera needs "Reading Mode" for opera like Edge browser to choose Dark background for web pages. i like older bookmark manager without preview. but...

Not related - you shouldn't post different issues in a thread. However, you can only specify a maximum number of columns. Opera does not change the size of speed dial tiles to make them fit. Unless you have a 4K monitor you can't fit 11 tiles in the window.

@temkem Perhaps the fix will be included also in the Opera 57, if not then most probably in 58, when it reaches beta channel. I can't tell this for sure, because I'm one of the users, not Opera's employee, and therefore I don't have access to any internal Opera's tools, like e.g. bug tracker system. For that, you need to receive reply from one of the employees.

Hi, you asked
@l33t4opera said in New Opera developer 58:
are you sure it happens only, when you access that site, and it doesn't occur for other websites?
In my previous post i wrote
@loup001 said in New Opera developer 58:
The strange think is it started about 2 - 3 months ago, and only when accessing certains new sites ...
To name them, msn, huffington post.
For sputniknews, that was the very first time this site was accessed from my network. I noticed that something was wrong, after several seconds of the spinning wheel icon running on tab with nothing showing on page.
Furthermore the ip 77.111.246.18 was not an address assign to any of my vpn locations.
@l33t4opera said in New Opera developer 58:
In some cases, it can be misinterpretation (false-positive) of the firewall/router, or simply defective packets, e.g. from already closed session. This may happen usually, when you use P2P software, and many connections are in use at the same time.
I do have a p2p software that i use only to download linux installers and nothing else. I have not used that software for the last year.
My router/firewall is program to block all upd request from wan to lan.
Thank's !

@leocg, my profile is only about a week old--as is my Opera installation. I realize a clean profile will correct the issue, but I'd rather try to fix my current profile because I really don't want to go through the whole setup and configure exercise again for all my tabs and such. Although, I appreciate your suggestions. Thanks.

Amazing, it is now possible to have a website create a popup window in Opera that you can't move and can't close... Unless you are fortunate enough to know about Alt-Drag to move or Alt-F4 to close... Oh, but wait, that doesn't work on a touch-screen does it?!

Like others on this thread, I too am now looking to an alternative unless it looks like this "feature" will be fixed. Vivaldi's looking nice so far.
Edit: Browsing around, found this page:
https://www.htmlgoodies.com/beyond/javascript/article.php/3471181/New-Window-No-Title-Bar.htm
Smiled at the comment from KS at the bottom: That only works in older browsers. Modern browsers won’t let you remove the title bar because then there’s no way to close the window.
Seems that is not so true anymore

I finally solved the issue: I first tried a clean install but used my previous profile. I still had the same problem, so then I started with a fresh profile and and had to "rebuild" my windows and tabs. But now when I start Opera my tabs are loading as expected.

Hi again @furret29, I have an idea regarding freezing text boxes, open the opera:flags, and type "idle" in the search box. You should see 3 flags: #infinite-session-restore, #page-almost-idle, and #proactive-tab-freeze-and-discard. Disable the last one, relaunch the Opera, and check if it helps, and if not, try to disable all three flags, and if it still doesn't help, try to revert back to build 57.0.3082.0, and if the issue is gone, you can wait until it will be fixed in one of the further builds - one of the users wrote here, that similar problem appeared, after he updated to latest version.
